IMPROVEMENT IN CAR-REPLACERS.

Specification forming part of Letters Patent No. 193,211, dated July 17,1877 application filed 'January 31, 1877.

To all whom it may concern Be it known that I, JEROME B. BARNES, ofIndianapolis, in the county of Marion, in the State of Indiana,` haveinvented a new and valuable Improvement in Oar-Replacers; and I dohereby declare that the following is a full, clear, and exactdescription of the same, both in operation and construction, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of side view of myinvention applied to a car. Fig. 2 is a sectional end view of the same;and Fig. 3 is a detail view of the caster.

This invention has relation to improvements in car-replacers for streetor steam cars.

The object of my invention is to provide an economical and expeditiousmeans for replacing cars of every description upon the track, after theyhave jumped7 the same, without requiring the passengers to leave theirplaces 5 for carrying cars around. sharp curves without causing theenormous friction incident to, and inevitable in, the present mode of sodoing; and, finally, for transferring a car from one track to anotherwithout injury to the car or its occupants.

The nature of my invention consists in combining, with a casterwheelhaving its bearings in a ratchet-box, and capable of rotating therein, atubular casing, adapted to receive said box, provided with a cog-wheelengaging said box, and means for operating said cog-wheel, as will behereinafter more fully set forth.

In the annexed drawings, the letter A designates a strong metalliccaster, consisting of a tapering shank, a, preferably of wroughtiron,and a strong broad-treaded roller, a', journaled in the lower end ofsaid shank or spindle. v

The shank or spindle aforesaid extends upward through a metallic boxorcasing, B, the bore of which is conical, and adapted to receive thesaid spindle, and the exterior walls of which are at right angles toeach other. This box is providedupon one of itsvfaces. with a series ofteeth, b. The spindle of the caster-wheel is coniined to the ratchet-boxB by means of a pin, c, which, while it allows the casterwheel to rotatefreely, will prevent it from dropping out of the said box. C representsa preferably metallic box, having a rectangular hollow or bore adaptedto admit the ratchet-box B within it, as shown in Fig. 2. This box ispassed up from below through a rectangular opening platform, and isbraced against vertical upward displacement by means of a socket, E, inwhich the upper end of this box is seated.

The socket aforesaid is-suitably connected to the platform by inclinedbraces K, that are rigidly secured to the platform at each side. Hrepresents a suitable cog-wheel, having its bearings in lugs t at oneside of casing C. This cog extends inward through a slot, M, in saidcasing or box, and meshes with the teeth of the ratchet-box aforesaid.Its journal extends outward a sufficient distance to have aratchet-wheel, I, and to be provided with a wrench-seat, a, on its end,outside of said ratchet wheel, by means of which a suitable crank-armmay be applied thereto.

By rotating the cog-wheel H the end of the car may be raised, and itstransportingwheels lifted clear of the track, when the car is to betransferred from one track to another, or in replacing the car from theground, and the caster-wheel being inclined in the direction of thetrack to be occupied, the application of the draft will cause the car totake the desired direction. The ratchet-wheel I aforesaid will beprevented from rotating backward by means of a pawl, y.

The spindle of the caster-wheel will, after the roller has been adjustedin the proper direction for replacing the car, be secured againstrotation by means of a set-screw, s, that passes through the outercasing and the ratchet-box, and bears forcibly against the said spindle.This screw also relieves the ratchet and its pawl of no inconsiderablestrain, as, after the end of the car is raised, it may be applied, andthus hold the ratchet-box rigidly in place.

Having thus explained claim as new and desire Patentmy invention, I

in the end of the carsecured thereon,
